LAMP-BURNER.

Specification of Letters Patent.

Patented Bee. 2%, 11921).-

Application filed May 11, 1920. Serial No. 380,843.

To all whom it may concern:

Be it known that I, MIoi-iAnL Onos, a citizen oi the United States, and resident of the city of Seattle, county of King, and State of Washington, have invented certain new and useful Improvements in Lamp- 'Burners, of which the following is a specification.

This invention relates to improvements in lamp burners or attachments for lamp burners and the object of this improvement is to provide means for preventing the flame of an ordinary railroad signal lamp from being easily extinguished.

This invention is in the nature of an improvement on, or an attachment for, the type of burner illustrated and described in my copending application, Serial Number 123179, although it is obvious that this device may be applied to any ordinary form of lamp or lantern burner.

The invention consists in the novel construction of a device for preventing a lamp from being extinguished and in the adaption. and combination of such device with a lamp burner, as will be more clearly hereinafter described and claimed.

In the accompanying drawings Figure l is a view in vertical section of a burner having this invention applied thereto.

Fig. 2 is a view in elevation of the device shown in Fig. 1.

Fig. is a view in perspective of a preferred form of the device.

Fig. 4- illustrates a modified form of the device shown in Figs. 1, 2 and 3.

Fig. 5 illustrates another modified form wherein the anti-extinguishing device is formed integral with the wick guide of the burner.

Fig. 6 is a view in perspective of a modified form of the device.

Fig. 7 is a view in perspective of another modified form of the device.

In the use of railroad signal lamps it is customary to use signal oil as fuel. One of. the reasons for this is that signal oil produces a flame that is not so readily extinguished when the lamp is swung in giving signals, as is a flame produced by kerosene or similar petroleum oil.

My previous invention, hereinbefore re ferred to, disclosed a burner that would prevent leakage of oil in a signal lamp, and

this invention discloses a device that will prevent the lamp flame from being readily extinguished when kerosene oil is used in the lamp.

In the accompanying drawings the numeral 9 designates a lamp burner that is provided with a wick guide 10 that projects from the top of the burner in the usual manner, and has an ordinary fiat lamp wick 11 provided therein.

12 is a metal band that is bent in the form shown in Fig. 3 and adapted to lit over the wick guide 10 like a spring clip.

13 is a vertical support that is secured to the band 12 by crimping the band around it, as at ll, and is adapted to project above the top of the wick guide when the band 12 is placed thereon.

The top end of the support 13 is bent at right angles thereto, forming a short arm 15 that is secured to and holds a cross bar in a position directly above the center of the wick guide 10 in such'manner that when the lamp is lighted the cross bar will lie within he flame 17 of the lamp, as shown by dotted lines in Fig. 2, and will divide or split the flame of the lamp.

Fig. 5 shows a standard 18, formed integral with the wick guide 10, and supporting downwardly curved integral arms 20 directly above the center of the. wick guide. The device shown in Fig. 5 operates in the same manner and attains the same result as the device shown in Figs. 1 to 3 inclusive.

Fig. 4 shows a device identical with the device shown in Figs. 1 to 3 except that the cross arms are curved upwardly on each side of the central support, thence dowir wardly, as at 21, and thence upwardly at their outer ends, as indicated at 22.

Fig. 7 shows a device similar to the device shown in Figs. 1, 2 and 3, except that the cross bar is formed integral with the arm 15 by bending it in the manner shown.

Fig. 6 shows the device formed of a single piece of wire, the lower portion comprising a loop 23 adapted to fit over a wick guide, and the vertical portion consisting of two upright members 24:, bent near the top, as at 25, and thence having the two ends turned outwardly to form arms 26 that are disposed directly above the center of the wick guide when the device is placed thereon.

It will thus be readily seen that the various forms of construction illustrated and described, all serve the purpose of supporting a small wire or bar directly above the center of the wick guide so that such bar will be within the flame of the lamp a short distance above the wick when the lamp is lighted. V

The cross arms in each of the forms illus trated and described are supported a short distance above the top of the wick guide parallel thereto, so that they will bevin the plane of the flame when the lamp is vertical and the length of such bars is less than the width of the flame.

The bar thus supported spreads or divides the flame and gives it a greater width and volume thereby making the flame more difiicult to extinguish.

The bar also becomes heated, after the lamp is lighted for a short period of time, and tends to gasify the fuel from the wick more rapidly, thereby increasing the vol- 7 ume of the flame and making it harder to put out. If the lamp is suddenly extinguished, after the cross bar has become very hot, it will be instantly relighted by the hot bar.

The heated bar within the flame of the lamp near the end of the wick also tends to prevent the lamp from smoking, owing to the fact that it helps to gasify the fuel and make a more combustible and inflammable gas.

The ends of the cross bar shown in Figs. 1 to 3 inclusive may be bent downwardly, as shown in Fig. 5, if desired.

It is obvious that changes in the form and construction of this device may be made within the scope of the appended claims.

7 the width of said flame.

l/Vhat I claim as new and desire to protect by Letters Patent, is:

1. The combination with an oil lamp having a burner provided with a wick guide that projects above the top thereof, of a spring clip adapted to fit over said wick guide, an upright support on said clip at the side of said wick guide and'a bar on the upper end of said support and disposed parallel and in alinement with the top end of said wick guide at a Short distance thereabove, the length of said bar being less than 2. An attachment for an oil lamp burner comprising a spring clip adapted to fit over the wick guide of said burner, an upright support carried by said clip and projecting above the top of said wick guide, an arm formed on the top end of said support at an angle thereto, and a cross bar carried by said arm and disposed parallel and in alinement with said wick guide at a short distance thereabove.

3. The' combination with an oil lamp burner having a wick guide, of a support extending upwardly from said guide and curved so that its upper end is over the top of said guide and a cross arm carried by said support directly above the center of said Wick guide and paralleltherewith whereby said cross arm will lie within the flame of said lamp when said lamp is lighted and prevent said flame from being extinguished.

Signed at Seattle, Washington, this 5th day of May, 1920.
